About This Location

The Palos Forest Preserves encompass over 14,000 acres in southwestern Cook County, making them the largest contiguous forest preserve complex in the Chicago region. The rolling terrain — unusual for the flat Chicago area — supports mature oak-hickory forest, prairie remnants, sloughs, and wetlands that host exceptional bird diversity.

The preserves are home to breeding species rare in the Chicago area, including Pileated Woodpecker, Barred Owl, and Red-shouldered Hawk. Spring migration brings warblers, thrushes, and flycatchers to the extensive forest, and the combination of water features and wooded uplands creates habitat diversity that supports over 250 recorded species. Key birding areas include Maple Lake, the Sag Valley, and the trails around Teason's Woods.
